SAFETY-RAZ OR.

FREDERICK GoEnTz, citizens of the Unitedl States, both residing atv Newark, in the county of Essex and State ot New Jersey.

'have invented certain new and useful 1mprovements in Safety-Razors, of which the following is a full, clear, and exact specification,

This invention relates to safety razors generally and more particularly to the type `of razor disclosed in the co-pending application of Harry 1V. Greenbrier, Serial Number 169,182, filed May 17, 1917.

lAmong the main objects of the present invention it is aimed to provide an adjusting means which can be manipulated with all possible speed, and which manipulation is so simple as to be apparent even to the most casual observer, thus to prevent the confusion that mightordinarily arise to the new user.

Another object of the invention is to provide a clamping member to coperate with a blade support, the connection between which not only serves to pivotallv connect the two, but in addition to transmit a clamping effect in the performance of certain of its functions. and also to form positioning abutments for the blade to be supported.

Still another object of the invention is to provide a device, the construction of the several parts of which are conducive to the long life of the article. the cost of manufacture of which is reduced to a minimum, and the working parts of which are so arranged to assure the continued effective operation thereof.

These and other features. capabilities and advantages of the invention will appear from the subjoined detail description of one specific embodiment thereof, illustrated m the accompanying drawings, in which- Figures 1 '2 and 3 are front, end and rear elevations ot' a razor made according to the present invention.

Specification of Letters Patent.

Application led August 10, 1917.

Patented Dec. 17, 1918. ,Serial No. 185,430.

Fig. i is an enlarged end elevation similar to that shown in Fig. f2 and partly in section.

A Fig. 5 is a view showing the several parts of the razor disassembled. In the embodiment illustrated, there is 'shown a lrazor comprising essentially a head A and a handle B'. The head A embraces the clamping member 6, the blade T and the blade support S. while the handle B embraces iie enlarged knurled portion 10 to facilitate grasping the same, and the hollow diminished portion orshank 11 in which the adjustin(r pin is disposed.

The b ade support 8 as shown in Figs. and -1 has a central portion 13 provided with a socket 14 internally screw threaded to receive the outer screw threaded port-ion 15 ot the diminished portion 1l and extending in a plane substantially at right angles thereto. rEhe front portion of the blade support is substantiallyv S-shaped in transverse section, with guard teeth 16 at the front end thereof. and elongated openings 17 just rear of the teeth to facilitate the cleansing of the same. The lateral portions 26 and QT ot' the blade support S extend to thev rear edge thereoil and' are disposedl substantially in a plane that is oblique to the diminished portion 11 and is provided with bayonet recesses 1S and 19 at its rear edge adjacent to its lateral sides. The portions 2G and 27 and the Sshaped portion of the blade support. together form a support that is substantially oblique relative to the diminished portion or shank 11.-

rlhe clamping member has an upright portion'QO which extends substantially parallel to the diminished portion or shank l1 when in place thereon, a lower lateral extension 21 extending substantially vat right angles to and from the lower end of theupright portionl 2G, and an upper frictional engaging portion extending downward from and at an oblique angle to the upright portion 20. The clamping member is furthermore provided with an oval aperture '223 to permit the passage therethrough ot' the diminished portion or shank l1. As shown in Figs. 2 and 5, the upright portion 2() is provided with fingers 'il and 25 that extend upward at an oblique angle to thc upright portion 20. but substantially at right angles to the lateral portions 2o and '2T ot the blade support S to enter the bayonet recesses 18 and 19. respectively.

The frictional engaging portion 2'2 will normally be disposed parallel to and substantiallyv fiat on the portions 2o and 2T of the blade support S. the fingers '2l and '25 and the recesses 1S and 1S) cooperating with one another respectively, to firmly clamp the portion '22 against the support S.

The apertur'e 23 aforesaid will be sutiiciently elongated to permitthe free moveinent ot' the clamping member (l relative to the extension il and permit tilting its frictional portion 22 relative to the blade support b.

The blade T is supposed to be clamped between the blade support and the tric tional engaging portion '22 and provided with lateral ears '2S and 29 at its rear edge which are spaced from one another to receive between them the fingers 'il and 25. which fingers and ears cooperate to guide the blade to proper position and secure the saine against lateral displacement. Ythe ears and 29 also extend laterallyv of the blade to ali'ord grasping means for positioning and removing such blade.

The upright portion 2O is also provided with. and has inclined therefrom. a tongue 32 which is adapted to engage the outwardly bulging portion 32% disposed between the lateral portions 2o and 2T of the blade support This tongue 22 cooperates with the bulging portion 33 to increase `the tension ot the friction engaging portion '32 against the blade i'. whereby the tension strain will be distributed between fingers :il and 25 and the tongue The. diminished portion or shank ll is clnnnbered to receive the pin l2 which is ope `atively mounted to project from the upper end otl such diminished portion to engage the. blade T. The diminished portion or shank 11 is provided with a cam slot 30 preierably near the lower edge ot the chaml'iered port-ion oic the diminished portion or shank l1 and extending from the chambercd portion to the outside to receive the cani pin 3l secured to'the pin 1Q. The pin 31 in the manipulation thereof will cooperate with thc slot 30 to elevate the pin l2 ,thereby to properlv engage and elevate the blade T and trictioiial engaging oortion to swing the saine to the inclination desired.

From the foregoing it will be. seen that lessees ready t'or adjustment it desired, Thereupon by the manipulation oi' the pin Si, the pin l2 may be positioned to secure the blade and triciional engaging portion at the inclination desired.

It is obvious that various changes and moditicatimis may be made to the details of construction without departing troni the general spirit and scope of the invention.
